TandemTrack: Promoting Consistent Exercise Leveraging Multimodal Training and Tracking.

As smart speakers such as the Amazon Echo have grown in popularity, these devices have presented new opportunities for exploring voice interaction, particularly in the domain of exercise. We have created TandemTrack, a multimodal system comprised of a mobile app and an Alexa skill whose capabilities include exercise guidance, data capture, feedback, and reminder. We propose using TandemTrack in a deployment study to explore and analyze individuals' preferences and use of voice and visual interactions, and to test TandemTrack's effectiveness as a whole in promoting consistent exercise habits while additionally comparing the effectiveness of the app against the skill. Not only does TandemTrack make important steps in addressing gaps in currently available exercise assistants, but also, more importantly, we believe this is the first study to investigate the specific value that voice interactions may provide over other technologies in promoting consistent exercise.
